Improved shoe-maker s edge-plane



NITED STATES CHARLES E. HERSEY, OF EAST STOUGHTON, MASSACHUSETTS.

IMPROVED SHOE-MAKERS EDGE-PLAN E.

Specification forming part of Letters-Patent No. 44,093, dated September(i, 1864.

T0 all whom, it may concern:

Be it known that l, CHARLES Hnnsnv, a resident of East Stoughton, in thecounty of Norfolk and State of Massachusetts, have invented an ImprovedShoe-Makers Edge- Plane; and I do hereby declare the same t0 be fullydescribed in the following specifica. tion and represented in theaccompanying drawings, of which- Figures l and 2 are elevations ofopposite sides of it; Fig. 3, an end elevation, and Fig. 4 a transversesection, of it, this figure having its plane of section taken throughthe clamp-screw of its gage.

The nature of my invention consists in making the adjustable knife, aswell as the adjustable gage thereof, of such edge plane with adovetailed rib, and the stock to which they are confined with jaws andclamping-screws, whereby such rib or ribs may be held to the stock, thewhole being as hereinafter described.

The object ot my invention is to hold either ot' the vmovable oradjustable parts of the stock firmly, and so that it may be easilyadjusted on the stock, or the two parts (the knife and the gage) beadjusted with respect to each other.

In the drawings, A denotes the stock, and B the handle thereof. The saidstock is constructed with a throat or chip-passage, C, leadingrthroughit laterally, and, furthermore, it is provided with a movable knife, D,and gage E, which are arranged on the stock in the manner as representedin the drawings. The upper surface of. the knife and its gage should besuitably shaped so as to impart to the edge ot'a sole, while beingdressed by the knife, the proper or desirable form.

ln carrying out my invention, I eonstluct the knife D, as well as thegage E, with a dovetailed rib, a, extending along that edge or part ofit which is to be placed against the stock. The rib of the knife is toenter betweenjaws b b', made in the stock, and by means ofa saw kerf 0rchannehc, which, where it receives the dovetailed rib, is to bedovetailed to correspond with and fit to it, jaws b2 b3 are also formedin the stock, to receive and grasp the rib a of the gage E. In order toenable the jaw b to be sprung toward its fellow jaw, a saw kerf orrecess, c, is madelaterally into the stock, as shown in Fig. 3.

There is also such another saw kerf or recess, c', made in one ofthejaws b b', by which the gage E is held to thelstock. A clampscrew,z', goes through one of the jaws b b and screws into the other. Asimilar clam pscreW, 7c, goes through the jaw b3 and screws into the jawb2. By means of thesescrews the jaws may be closed with great firmnesson the ribs when betwren them, as shown in the drawings. Thesejaws withthe dovetailed ribs not only very strongly hold the knife and its gageto its stock, but enable either or both ot' them to be adjusted thereonor relatively to each other as circumstances may require fhen either theknife or the gage is held to the stock by a screw going through a slotin the stock, it is apt, while the edge-plane is in use, to be movedmore or less out of place, and cannot be relied on to keep in its place,as it will when held by a dovetailed rib, jaws, and a clamping-screw.

With my improvement, the clampingscrew does not screw into either thegage or the knife, and therefore it is not liable to be moved by itwhile such knife and gage may be in use. While the dovetailed rib andjaws hold the knife and gage closely in place in the stock, and preventthem from dropping therefrom while being adjusted, the great eX- tent ofbearing-surface operates to great advantage in preventinganylongitudinal movement of the said gage or knife relatively to thestock.

I do not claim an edge-planeas made in any manner as represented in theUnited States latent No. 27,840, my invention being an improvement withreference thereto.

I claim- My improved edge-plane, as explainedthat is, as having itsknife or cutter, as well as its gage, provided with a dovetailed rib,and its stock constructed with corresponding jaws, made in manner andprovided with the notches c c', and furnished with a clampingscrcw, asdescribed, the same being as and for the purpose or objects ashereinbeforc explained.
